Measure small changes in air pressure with these hand-held gauges. They have a four-digit LCD display for easy reading of measurements. Gauges are commonly used to indicate clogged filters and to monitor fans and blowers.

Easier to read than U-tube gauges, these use an inclined scale to measure pressure or velocity in air applications. Gauges are also known as manometers.

Gauges have a four-digit LCD display for easy reading of measurements. Commonly used to indicate clogged filters, these gauges display the difference between two pressure or vacuum measurements. They are also known as compound gauges.

With a digital display and selectable differential pressure ranges, these transmitters are a versatile alternative to transmitters with dial indicators. Unlike a standard transmitter that has one wider differential pressure range, these transmitters have multiple ranges to choose from. The selectable pressure range means they are more accurate than standard transmitters since their accuracy applies to each small range rather than a single wide range. They can also be configured to output either current or voltage, while standard transmitters typically output one signal type. The digital display allows you to troubleshoot and monitor differential pressure at the source. Also known as transducers, they measure the difference in pressure between two inputs and convert it to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls. They are often used to indicate a filter is clogged or help you maintain a certain air pressure in ovens, dryers, and HVAC systems. All are rated UL 94 V-0, so they meet flammability standards. CE marked, they also meet European safety standards.

When measuring pressure in ductwork, pair them with a static pressure probe. Transmitters with an 8" pressure probe cable include a static pressure probe.

For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's differential pressure range and output signal. As differential pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range.

Connect them using two wires when using the current output. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. For voltage output, connect them using three wires—two wires into the power supply and a separate wire to send a signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply.

DIN-rail/surface mount transmitters give you mounting flexibility. They include the bracket you'll need for mounting it to DIN rail.

Transmitters with a calibration certificate traceable to NIST have passed tests for accuracy.

Transmitters that meet IP67 protect against dust and submersion.

Check the difference in air pressure between two inputs at the source using the dial indicator or remotely using a receiver. The dial indicator on these transmitters operates independently and shows differential pressure in real time for troubleshooting. Also known as transducers, these transmitters convert pressure to an electrical signal that is interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls. They are often used to indicate a filter is clogged or help you maintain a certain air pressure in ovens, dryers, and HVAC systems. All are CE marked, so they meet European safety standards.

Used with pumps, cooling systems, and other liquid applications, these transmitters remotely measure the difference in pressure between two inputs. They are also known as transducers. These transmitters convert differential pressure to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment. You’ll often see them used to indicate a filter is clogged.

IP66 rated transmitters are dust tight and protect against washdowns. NEMA 4X rated transmitters protect against weather, washdowns, and corrosion.

At least twice as accurate as standard transmitters, these transmitters sense differential pressure at an accuracy of ±0.25%. Use them in laboratories or testing applications where the difference in pressure between two points needs to be measured with high accuracy. These transmitters are often used to indicate a filter is clogged or help you maintain a certain pressure in pumps, HVAC, cooling, and other air and liquid systems. They convert differential pressure to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment. All transmitters are rated NEMA 4 for protection in washdown environments.

With an accuracy of ±0.05%, these have the highest accuracy of all our test gauges. Use them for testing, calibrating, laboratory applications, and other critical processes that require precision. They have a five-digit LCD display that allows for easy reading of measurements.

For easy panel mounting in your water system, these valves have threads below the adjustment knob and come with a panel-mount nut. They automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. Body is polysulfone, which is lightweight and corrosion resistant.

Compression fittings bite down on hard metal and plastic tubing for a tighter seal than push-to-connect fittings. These valves automatically reduce a high, variable inlet pressure to a lower, stable outlet pressure. Adjust the outlet pressure within the range. The Buna-N/stainless steel diaphragm and EPDM seal are FDA compliant 21 CFR 177.2600.

Automatically reduce a high, variable inlet pressure in your steam system to a lower, stable outlet pressure. Adjust the outlet pressure within the range. These valves have a cast iron body that absorbs vibration from pressure changes to reduce wear and noise in your pipeline.

Threads below the adjustment knob and an included panel-mount nut allow you to add these valves to your instrument panel. Often used in systems running on air compressors, they're installed after pressure-sensitive equipment to obstruct flow and maintain a consistent operating pressure. If the system pressure exceeds the set pressure, they exhaust through the outlet. Adjust the set pressure within the range.

A lower profile than our other compressed air regulators makes these regulators a better fit in tight spots. Use them to adjust and maintain the pressure of your compressed air. Install in your air line after filters.

Relieving regulators exhaust when the downstream pressure exceeds the set pressure.

Mounting brackets allow you to attach the regulator to a wall or equipment.

With a greater flow capacity than our standard precision compressed air regulators, use these regulators to adjust and maintain air pressure in sensitive high-flow applications where constant, consistent pressure is important. Install in your air line after filters.

Relieving regulators exhaust when the downstream pressure exceeds the set pressure.

Nonrelieving regulators do not exhaust excess downstream pressure.

Pressure gauges are for use with regulators with NPT threading.

Mounting brackets (sold separately) allow you to attach the regulator to a wall or equipment.
